This isn't going to be any help..I've not seen the manual you're referring to...BUT...kawi adjustments I think are ALL CW='more', CCW='less'.
I'd go with what's on the shock in any case.
Recommended settings? I know that answer. It's NO answer!
The tuner that setup your stuff could give you a close figure. Otherwise, without knowing your valving setup, spring rate, weight and something a bit more concise than 'bumpy' I'll venture that anything anyone told you would be bogus.
There's a method for setting shock compression/rebound. The pro-action website has a writeup on it. Jeremy used to (mx-tech). Last time I looked, I didn't see it anymore.
The two were similar, the process being the same in any case. The pro-action site is:

Basically, compression loose enough so it doesn't 'pack', rebound tight enough that it doesn't 'kick'.
